|
||
<p>A <a class="link" href="GtkSpinButton.html" title="GtkSpinButton"><span class="type">GtkSpinButton</span></a> is an ideal way to allow the user to set the value of
|
||
some attribute. Rather than having to directly type a number into a
|
||
<a class="link" href="GtkEntry.html" title="GtkEntry"><span class="type">GtkEntry</span></a>, GtkSpinButton allows the user to click on one of two arrows
|
||
to increment or decrement the displayed value. A value can still be
|
||
typed in, with the bonus that it can be checked to ensure it is in a
|
||
given range.</p>
|
||
<p>The main properties of a GtkSpinButton are through an adjustment.
|
||
See the <a class="link" href="GtkAdjustment.html" title="GtkAdjustment"><span class="type">GtkAdjustment</span></a> section for more details about an adjustment's
|
||
properties. Note that GtkSpinButton will by default make its entry
|
||
large enough to accomodate the lower and upper bounds of the adjustment,
|
||
which can lead to surprising results. Best practice is to set both
|
||
the <a class="link" href="GtkEntry.html#GtkEntry--width-chars" title="The “width-chars” property"><span class="type">“width-chars”</span></a> and <a class="link" href="GtkEntry.html#GtkEntry--max-width-chars" title="The “max-width-chars” property"><span class="type">“max-width-chars”</span></a> poperties
|
||
to the desired number of characters to display in the entry.</p>

<p>GtkSpinButtons main CSS node has the name spinbutton. It creates subnodes
|
||
for the entry and the two buttons, with these names. The button nodes have
|
||
the style classes .up and .down. The GtkEntry subnodes (if present) are put
|
||
below the entry node. The orientation of the spin button is reflected in
|
||
the .vertical or .horizontal style class on the main node.</p>

initially set to the minimum value and a page increment of 10 * <em class="parameter"><code>step</code></em>
